 你分配了col=end; b[k]=(double*) calloc (col,sizeof (double)); col=end; b[k]=(double*) calloc (col,sizeof (double)); 但你在循环中for(j=start;j<=end-1;j++){ b[i][j]=b[i][j+1]; } b[i][end] for(j=start;j<=end-1;j++){ b[i][j]=b[i][j+1]; } 在函数中。 computeDeterminant 。 你设置col=end+1; 或者你改变<= by < 。 
 
if(matrix == NULL)
    return 0.0;

row = end;
col = end;
double ** b=(double **) malloc (row*sizeof (double*));
for(k=0; k<row ;k++){
    b[k]=(double*) calloc (col,sizeof (double));
}

for(i=0;i<end;i++){
    for(j=0;j<end;j++){    
        b[i][j]=matrix[i][j];
    }
}

for(i=0;i<end-1;i++){ // i<end-1 bcause of i+1  
    for(j=1;j<end;j++){ // j<end
       b[i][j]=b[i+1][j];
    }
}

for(i=0;i<end;i++){ // i<end
    for(j=start;j<end-1;j++){ // j<end-1 bcause of j+1
        b[i][j]=b[i][j+1];
    }
}
 
 此外，您应该释放在函数computeDeterminant为b分配的内存 
 
if (end-1==2){
    s = b[1][1]*b[2][2]-b[1][2]*b[2][1];
}
else{
    for (j=0;j<end-1;j++){
        s=s+pw(1+j)*b[1][j]*computeDeterminant(end-1,j,b);
    }
}

for(k=0; k<row ;k++){
    free( b[k] );
}
free(b);

return s;
 
 在函数sum存在类似的问题： 
 
double sum(int n,double **matrix)
{
    int j;
    double s=0;

    if(n>2)
    {
        // for(j=1;j<=n;j++) <- change this
        for(j=1;j<n;j++)
               //^
            s=s+pw(1+j)*matrix[1][j]*computeDeterminant(n, j, matrix);
        return s;
    }
    else
        return matrix[1][1]*matrix[2][2]-matrix[1][2]*matrix[2][1];
}

You allocated col=end; b[k]=(double*) calloc (col,sizeof (double)); but you accesed to b[i][end] in loop for(j=start;j<=end-1;j++){ b[i][j]=b[i][j+1]; } in function. computeDeterminant. Either you set col=end+1; or you change <= by <.
 
if(matrix == NULL)
    return 0.0;

row = end;
col = end;
double ** b=(double **) malloc (row*sizeof (double*));
for(k=0; k<row ;k++){
    b[k]=(double*) calloc (col,sizeof (double));
}

for(i=0;i<end;i++){
    for(j=0;j<end;j++){    
        b[i][j]=matrix[i][j];
    }
}

for(i=0;i<end-1;i++){ // i<end-1 bcause of i+1  
    for(j=1;j<end;j++){ // j<end
       b[i][j]=b[i+1][j];
    }
}

for(i=0;i<end;i++){ // i<end
    for(j=start;j<end-1;j++){ // j<end-1 bcause of j+1
        b[i][j]=b[i][j+1];
    }
}
 
Further you should free the memory you allocated for b in function computeDeterminant
 
if (end-1==2){
    s = b[1][1]*b[2][2]-b[1][2]*b[2][1];
}
else{
    for (j=0;j<end-1;j++){
        s=s+pw(1+j)*b[1][j]*computeDeterminant(end-1,j,b);
    }
}

for(k=0; k<row ;k++){
    free( b[k] );
}
free(b);

return s;
 
In function sum there is a similar problem:
 
double sum(int n,double **matrix)
{
    int j;
    double s=0;

    if(n>2)
    {
        // for(j=1;j<=n;j++) <- change this
        for(j=1;j<n;j++)
               //^
            s=s+pw(1+j)*matrix[1][j]*computeDeterminant(n, j, matrix);
        return s;
    }
    else
        return matrix[1][1]*matrix[2][2]-matrix[1][2]*matrix[2][1];
}
